    Great barrels with sub – MOA accuracy

  2. Baron Buehler (verified owner)

    So far so good, however have not done any range time as of yet. However have great expectations as B King is GTG with there products.

    I am completely impressed with BKF and know they have my best interests protected. I have made two orders and both have been perfect. They are always willing to pick up the phone and discuss the parts they provide, which is a great reassurance. I am sure the AR I am assembling now for my son, will be a VERY nice carbine with the BKF parts utilized. Not sure what else can be said other than, “I trust BKF” Thank you guys!

    Have yet to bring this barrel out to the range but initial impressions are good. No excess machining marks and the feed ramps are cut very well. The included gas block was nice and low profile and was simple to install. Will revisit this review with range results.

    Update 6/9/2020
    We took the rifle out to the range and put about 500 rounds through this barrel throughout the day. I am happy to report that it held a 1-2 inch group consistently throughout the day out to 100 yards. We were bench shooting the rifle as well as transition drills so it got a good variety of use and didn’t skip a beat. No complaints at all!

    This barrel with a pinned and welded flash hider is pure bliss.

  7. Jeff Scarpace (verified owner)

    Very nice barrel and the pinned gas block was spot on. Very accurate and fit tight in the BKF Mod1 upper. Really liking this set up.

    It was shipped and received promptly! Great price for the barrel and gas block, you would be hard pressed to beat it. The barrel was packaged nicely and it looks very well made. I will be shooting it on the 27th of April, I can update then about performance.
